Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an annular object counting device and an annular object counting method for counting annular objects such as transmission belts, rubber bands and O-rings.
[0002]
[Prior art]
The transmission belt, which is an annular material, is usually bundled by counting a predetermined number of belt belts that have been vulcanized and formed by cutting the belt material at regular intervals. Conventionally, as an annular material counter that automatically performs this counting operation, a transmission belt is suspended on an annular material holding plate provided above a conveyor belt, and the transmission belt is gradually pushed out by an extrusion device, thereby separating the interval. The transmission belt is dropped onto the conveyance belt while leaving a gap, and the transmission belt is conveyed toward the open end by the conveyance belt. After this, the roller provided with a predetermined gap between it and the conveyor belt is rotated in the opposite direction to the conveyor direction, and if there is an overlap in the transmission belt, the upper transmission belt is retracted by contact with the roller. To remove the overlap. Then, the transmission belt is counted by the detection sensor, and when the predetermined number is counted, the tip of the rod is advanced and brought into contact with the uncounted transmission belt, so that the uncounted transmission belt becomes the counted transmission belt. It is configured to prevent mixing (for example, see Patent Document 1).

The annular object counting apparatus 1 according to this embodiment applies a plurality of annular objects, such as a toothed belt, a V belt, and a flat belt, by applying a tension by suspending a transmission belt on two axes of a drive shaft and a tension shaft. An alignment portion 2 that rotates and aligns only the shaft, a holding member 3 that pivots around the drive shaft to lift the annular object from the drive shaft, and an annular object suspended from the holding member at a predetermined pitch in the axial direction of the holding member And a counting mechanism 5 that counts the number of the annular materials fed from the end of the holding member.
[0014]
In the alignment portion 2, a plurality of annular objects 13 are arranged between a drive shaft 11 having a substantially circular cross section fixed to the support column 10 and a movable tension shaft 12 capable of adjusting the distance between the shafts 11. The plurality of annular objects 13 can be aligned by rotating only the drive shaft 11 by applying a tension to the suspension. The rotation of the drive shaft 11 is transmitted from the prime mover 14 via the transmission belt 15, but the transmission belt 15 is suspended between the pulley 16 attached to the drive shaft 11 and the pulley 17 attached to the prime mover 14. Is transmitted from the transmission belt 15 to the drive shaft 11.
The drive shaft 11 is coated on its surface with an elastic body that enhances frictional resistance, such as urethane elastomer or rubber, to prevent alignment and damage of the annular object 13 when the drive shaft 11 rotates.
[0015]
On the other hand, the tension shaft 12 has a substantially circular cross section, and one end of the tension shaft 12 is fixed to a guide member 19 fitted to a guide rail 19 arranged in the longitudinal direction (vertical direction in the figure) on the support column 10 and is cantilevered. And one end is fixed to the rod 22 of the cylinder 21. When the cylinder 21 operates, the tension shaft 12 moves up and down along the guide rail 19 to adjust the inter-axis distance from the drive shaft 11.
[0016]
In the holding member 3, as shown in FIG. 2, as shown in FIG. 2, a pulley 24, which is fixed at a position deviated from the center position by a metal bar 23 having a circular arc cross section, is fitted to the drive shaft 11 so as to be able to idle. It is connected to a rotary reactor 26. When the rotary reactor 26 rotates 180 degrees, the swab 23 rotates 180 degrees around the drive shaft 11 to forcibly lift the annular object 13 from the drive shaft 11, and the annular object 13 is locked to the disengager 23. Let
